Hands-off Time: spec planner, auto-merge on Approve + green checks, next card, update workflow

- spec issues (label spec) become queued cards, parsed deterministically, seat fallback
- TIME_AUTOMERGE=on: squash-merge when the latest trusted verdict is Approve and all checks pass
- Object, red or missing checks, or protected paths go to needs-human
- merged card frees the slot; the next unblocked queued card gets ready and dispatches in the same run
- update.yml pulls the engine from teahubxyz/time into project repos via PR
- ci.yml runs Time's own tests
